And within Shapes there is a group of Lines. Most of them are Connectors that can be attached to any of the illustrations and connect them with any others. The last three lines in the group, namely Curve, Freeform Shape, and Scribble, are not Connectors, but allow you to enrich the Excel collection of graphical creations with your own customized shapes/drawings.
Here's an example of possibilities offered by precise connections of the shapes. Just a simple idea:
- select appropriate connector from the Lines collection
- click anywhere on the first graphic element; connection points will appear for you to choose one of them and attach the connector line
- drag the cursor to a connection point on the second connection object
- to adjust appearance of the line, you can right-click on it and choose "Format Shape" to modify the line colour, thickness, style etc.
